What is advanced osteoarthritis?
Osteoarthritis (OA) is a chronic degenerative disease. It causes damage to your joints, including those in your:
- hands and fingers
- lower back
Treatment for OA focuses on managing your symptoms. The disease can’t be reversed.
The progressive degeneration of OA has been classified into four stages. The first stage, with no joint damage, is called Stage 0.
Stage 4 is the most advanced and severe stage of OA. Here are some signs of stage 4 OA:
- your cartilage is worn away
- the space between the bones in your joint is greatly reduced
- your joint is warm and inflamed
- the normal lubricating fluid of your joint is decreased, although the joint may be swollen
- you have more bone spurs and bone rubbing against bone at the joint
People with advanced OA have pain and discomfort moving the joint. The pain is often severe. It can be debilitating and prevent you from carrying out your daily activities.
How quickly does
osteoarthritis progress to stage 4?
The progression of OA depends on the severity of the disease at your diagnosis, the joints involved, and your general health. There aren't any drugs yet that can stop the deterioration. However, following a therapy regimen early in the disease can help slow the rate of degeneration.
Progression to stage 4 can take years or even decades. For very advanced OA, pain management and surgery or joint replacement may be recommended.
A found that OA of the knee progressed more rapidly in people who:
- were older
- had a high body mass index (BMI)
- had more than one joint involved
A noted that BMI affected the progression of knee OA, but not hip OA, although other studies have linked osteoarthritis of the hip and obesity.
What are the symptoms?
Pain and stiffness, especially in the morning, are the main symptoms of OA. If you have stage 4 OA, these symptoms can be severe and disabling.
Other symptoms include:
- loss of flexibility in the joint
- grating or crackling noise when you move the joint
- bone spurs, which feel like hard lumps, around the joint
- swelling around the joint
If your hands are involved, it may be hard to do things that require dexterity or grasping. If your knee or hip joints are involved, it may be extremely hard to walk, climb stairs, or lift objects.
What causes osteoarthritis to
The cause of osteoarthritis is now thought to be a combination of these factors:
Your genes may be involved in the development of osteoarthritis, though are still working to fully understand this connection. It may be that you have an abnormality in the makeup of your cartilage, or that your bones fit together abnormally at the joint.
Extra weight can put pressure on your hips and knees, which can cause the cartilage in your joints to deteriorate faster. The reports a link between being overweight and an increased risk of OA of the hand. Excess fat tissue is thought to produce chemicals that inflame and damage your joints.
Joint injuries or repetitive motion can lead to cartilage breakdown and OA. If the muscles supporting your joints are imbalanced or weak, this can also lead to cartilage breakdown.
Can you slow the progression
How to slow the progression of OA is not fully understood, although there are many standard therapies that can help at earlier stages of the disease.
- Physical therapy and exercise can help you strengthen the muscles around the affected joint.
- Weight loss can take pressure off your lower body joints.
- Regular exercise and stretching can improve flexibility, relieve stiffness, and improve your overall physical condition.
- Knee braces, hand splints, shoe orthotics, or other appliances, such as a cane, can help stabilize your joints.
How is advanced
In earlier stages of OA, you may find relief from physical therapy, regular exercise, weight loss, and assistive devices that help with your stability.
As your condition progresses to the advanced stages, your doctor may recommend additional treatments, including:
- cortisone injections to relieve pain in the joint
- hyaluronic acid injections to cushion the knee and provide pain relief
- pulsed electromagnetic field stimulation for OA of the knee
- electrical nerve stimulation for pain relief
- acupuncture for pain relief
- massage therapy for the affected area
- applying heat or cold to the painful joint to increase blood flow and ease pain
- supplements, such as glucosamine or chondroitin sulfate, which may bring relief for some people (though show mixed results)
- taking an avocado-soybean unsaponifiables supplement, which is used in Europe as an anti-inflammatory for knee and hip OA, and slow down joint damage
By stage 4, the cartilage loss and condition of your bones may drastically curtail your activity and comfort, making pain medication and surgery your main options.
In some cases, such as if you have damage to one side of your knee, a surgeon may realign the bone by cutting out a piece or adding more bone. This is called an osteotomy.
Another form of surgery is arthroscopic debridement. For this procedure, the doctor may remove loose pieces of bone and cartilage from the joint. However, with advanced OA, arthroscopy has very little to offer and doesn’t prevent the progression of the disease.
If your joint is severely damaged, the surgeon may replace the joint. This is called arthroplasty, or knee joint replacement surgery, and means the damaged parts of the joint are removed and replaced with plastic or metal parts.
If you have persisting pain, talk to your doctor about what painkillers might work best for you. If over-the-counter non-steroidal anti-inflammatory drugs (NSAIDs) aren’t effective, your doctor may prescribe something stronger. Other types of drugs include:
- COX-2 inhibitors
- tramadol (Ultram)
- capsaicin topical skin cream
Narcotics should be a last resort because of their side effects.
What's the outlook?
OA now affects . It’s most common in people over age 65. Discomfort and pain can be managed early on in the disease, and therapy can be effective in maintaining good mobility.
Advanced OA can be extremely painful and debilitating. With stage 4 OA, you may not be able to walk, climb stairs, or carry out your daily activities. You may need to have assistance at home and for transportation. You may not be able to work. Painkillers are an option, but can have side effects. Surgery followed with physical and occupational therapy can provide pain relief and allow you to continue functioning.
Ongoing medical research shows promise for finding ways to , heal cartilage, and trigger bone growth. New treatments may become available in the future.
